GEOLOGY

Detailed explanation-1: -The Vulcanian type, named for Vulcano Island near Stromboli, generally involves moderate explosions of gas laden with volcanic ash. This mixture forms dark, turbulent eruption clouds that rapidly ascend and expand in convoluted shapes.

Detailed explanation-2: -Introduction. Vulcanian eruptions are moderately explosive but intermittent, producing moderate ash columns. These eruptions are more explosive than Strombolian, and sometimes destroy part of the volcanic edifice. Vulcanian eruptions are propelled by exsolution of volatiles in magmas beneath a solidified plug of lava.

Detailed explanation-3: -Pyroclastic flows can occur during explosive eruptive activity, where the mixture of gas and ash emitted from the volcano is too dense to rise buoyantly into the atmosphere, Instead, it collapses around the volcano.

Detailed explanation-4: -Strombolian eruptions are driven by the bursting of gas bubbles within the magma. These gas bubbles within the magma accumulate and coalesce into large bubbles, called gas slugs. These grow large enough to rise through the lava column.

Detailed explanation-5: -A volcanic eruption is when lava and gas are released from a volcano-sometimes explosively. The most dangerous type of eruption is called a ‘glowing avalanche’ which is when freshly erupted magma flows down the sides of a volcano.
